commands defined in ITU T.30.
I don't see them in T.30, but it's not exactly easy to find stuff in there.... 


Where to get informations to add this commands
to the T.38 dissector?
ITU-T Recommendation T.30? :-) That'd either give you information to add them, or tell you that they're non-standard. 

Or is this a case of reassembly not being done?

Do you have a sample capture with this problem?
